SHOE SOLE Filed Jan. 10, 1959 Inventor Patented Sept. 24, 1940 UNITEDSTATES PATENT @FFHCE 1 Claim.

The present invention relates to'new and useful improvements in shoesoles and has for its primary object to provide, in a manner ashereinafter set forth, an article of this character comprising a novelconstruction and arrangement whereby durability and comfort will bematerially increased.

Other objects of the invention are to provide a shoe sole of thecharacter described which will be comparatively simple in construction,light in weight, attractive in appearance and which may be manufacturedat low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawing whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure l is a bottom plan view of a shoe provided with a soleconstructed in accordance with the present invention.

Figure 2 is a longitudinal sectional view through the invention.

Figure 3 is a detail view in perspective of the Wear resisting disk.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a sole1 of 30 leather having formed therein a tapered, circular opening 2. Thereference numeral 3 designates a portion of the upper of theshoe towhich the sole l is attached in the usual manner and 4 designates theheel of the shoe.

Threaded into the opening 2 and permanently secured therein by cementingis a tapered disk 5 of suitable flexible wear resisting material,preferably rubber or corded rubber. As illustrated to advantage in Fig.3 of the drawing, the periphery 4,0 of the tapered disk 5 is threaded,as at 6.

It will be observed that the disk 5 is located substantially beneath theball' of the foot when the shoe is in use where the greatest wear andflexing occur. It will thus be seen that the life of the sole will beconsiderably prolonged due to the greater wear resisting quality of thedisk 5. Also, 5 as a result of the greater flexibility of the disk 5 ascompared with the leather from which the sole I is made comfort to thewearer will be greatly increased. The taper of the circular opening 2 isfrom the upper or rough side to the smooth or 10 v lower side of thesole 1 and, therefore, the disk 5 is inserted from the upper or roughside before the sole is applied to the shoe. The invention may beincorporated in new shoes or in repair" soles. In the latter case therepairman may shift 15 the sole in any direction within certain limits,of course, before securing said sole to position the disk 5 as desired.In addition to increasing wear and comfort, the disk 5 is adapted toabsorb considerable of the shock to which the ball of the 20 foot issubjected. Of course, the disk 5 may be of any suitable diameter.

It is believed that the many advantages of a shoe sole constructed inaccordance with the present invention will be readily understood and 25although a preferred embodiment of said sole is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction may be resorted to which will fall within the scope of theinvention as claimed.

What is claimed is:

In a shoe, a leather sole having a circular opening in the ball portionthereof, said opening tapering from the upper face of the sole throughthe lower face, a disk of resilient material of sub- 35 stantially thesame thickness as the thickness of the sole and threaded in the openingand cemented in said opening with its upper and lower faces flush withthe upper and lower faces of the sole.
